Morrowind is the third game in the Elder Scrolls series. It takes place in Vvardenfell, an island in Morrowind. The main quest centers around taking down Dagoth Ur, the leader of House Dagoth, who has used the Heart of Lorkhan, a large, heart-like artifact of great power, to make himself immortal, and now seeks to drive the Imperial occupiers from Morrowind using his network of spies and followers.

Morrowind is a great game to play. Like any Elder Scrolls game, it's storylines are involved. It has different areas that look real. The game is called Morrowind but it actually takes place on the island of Vvardenfel (the rest of Morrowind sort of encircles the island except for a little area to the north, see a map to see what I mean) It's a volcanic island that has many geographical features. Most of the island is uninhabitable lava lands, but there is a fertile plain area in the northeast corner where most of the natives live. Also pretty much of the western and southwestern island is habitable. This is where most of the populated towns are. The main plotline centers around your character who just left prison and is being delivered to Vvardenfell by orders of Emperor Uriel Septim VII. After a storm and a strange vision in his dreams, the player begins fresh off a boat from a mainland prison in a town called Seyda Neen, freed by the string-pulling of the current ruler of the Tamrielic Empire, Emperor Uriel Septim VII, with the task of meeting Caius Cosades, a member of the Blades, a secret group tasked with the protection of the Emperor and the Empire.

Cosades inducts the player into the Blades under orders of the Emperor, and sets the player on various quests to uncover the mysterious disappearances and revelations that the citizens of Vvardenfell have experienced, particularly the Sixth House and the Ashlander prophecies of the Nerevarine. It is later revealed that The Sixth House, and Dagoth Ur, has been directly influencing the people within their dreams, including attempts to invade the player's mind.

Prophecies from the nomadic people living in the Ashlands, The Ashlanders, predict that Nerevar's incarnate will fulfil a set of seven prophecies. The first two prophecies are that Nerevar will be born on a certain day to uncertain parents, and will be cured of Corprus disease. Fulfilling these, the player seeks to complete the third prophecy, a test to find the Moon-and-Star, the symbolic ring worn by Nerevar, which would instantly kill any other who tried to wear it. Once the player finds and equips the ring, he receives a vision from Azura, the ancient Daedric Prince of the Dawn and Dusk, who confirms that the player is Nerevar's incarnate. Nerevar completes the fourth and fifth trials, which are to rally the Great Houses and Ashlanders of Vvardenfell under one banner. After receiving the support and being declared "Hortator" of the Great Houses and "Nerevarine" of the nomadic Ashlander tribes, the player is officially, albeit reluctantly, called "Nerevarine" by the Tribunal Temple, who normally persecute anyone who claims to be the Nerevarine and sentences them to death.

Nerevar is invited to the palace of the poet god-King Vivec to discuss the assault on Dagoth Ur's stronghold in the heart of Red Mountain. Vivec presents the player with the artifact gauntlet Wraithguard, an ancient Dwemer artifact that can use the tools of 'Sunder' and 'Keening'. The ancient implements will destroy the fabled Heart of Lorkhan, but without having the Wraithguard equipped, it will deal a fatal blow to whoever wields it.

The player travels into Red Mountain to Dagoth Ur's citadel. After talking with Dagoth Ur, who attempts to sway the player to his side with the claim that he is merely following Nerevar's final orders, the player and Dagoth Ur fight. Besting Dagoth Ur, the player breaks the Heart of Lorkhan with Kagrenac's tools, destroying the source of Dagoth Ur's power and killing him in the process. Akulakhan's Chamber where Lorkhan's heart resides is destroyed, and in turn Red Mountain is cleared of blight and The Sixth House falls. Upon escaping from the chamber, Nerevar is congratulated by Azura, who appears before him to reward his efforts of fulfilling the prophecy.
